要約
(EN)

In an ophthalmological device, a memory stores a three dimensional data set acquired by applying OCT to a subject's eye. A fourth color coding unit assigns color information according to a depth position to the three dimensional data set. A fourth layer region identifying unit identifies layer regions by applying segmentation to the three dimensional data set, A fourth blood vessel region extracting unit extracts a blood vessel region from each of the layer regions identified. A fourth front image constructing unit constructs a front image based on each of the blood vessel regions extracted. A fourth image composing unit composes at least two of the front images constructed based on the color information, to construct a composite front image.
